Reideen the Brave

After twelve thousand years of sleep, the Demon Empire wakes to take control of the Earth. Raideen, the giant robot-like guardian of the lost continent of Mu, feels the evil presence and awakens inside its golden pyramid. A young Japanese boy, Akira Hibiki, is warned about the Demon Empire by a mysterious voice and hurries to the pyramid. It is soon revealed that Akira is a descendant of the ancient people of Mu, and he must help Raideen save the Earth. Akira enters the robot by way of a ramp, accelerating his motorcycle into the robot's head and taking control of Raideen from an internal cockpit. In typical anime style, Akira is helped by Mari Sakurano, who happens to be the daughter of a prominent scientist, and his friends from the soccer club. Halfway through the story, the Demon Empire's master, Barao, is released from his statue prison and intends to finish what he started twelve thousand years earlier.
